Tyre pressure's, help please!

[witchywoo]

I'm sure I saw a thread on this but for the life of me I can't find it!
I haven't checked my pressures since i got my car (couple of months, bad girl!!) and wanted to do it.
my pressures on the inside of my petrol cap are in bar but my tyre pumper upper has PSI (yes i'm rubbish but i'm trying!!).
what tyre pressure does eveyone use in psi (or does anyone have a link to a conversion chart?!!).

thanks for your help!!

around 31/32psi is comfy for me :)

[witchywoo]

cool thanks! i'm always scared that i'm gonna pop 'em by pumping 'em up too high!! :o

[Blue_Smoothie]

nah u can go higher than that but i dont - i find its just right. same all round too. see i dont usually carry heavy loads or more than 1 person round so i dont worry about it too much :)

[witchywoo]

yeah i'm the same. will give it a go, does it make that much difference to the ride?

[DARYL_-_BMS]

with the 16's I used to run 29/30psi (which are the size of your tyres)

with 20's it's 42 psi!

[Shamrockez]

My 16s look really soft at 30psi

[bug78]

check under the petrol cap it says there hope this helps :)

My petrol flap doesn't have any - I replaced it with a new one ;D

[antix_v2]

What should the pressures be on 18's?

[DARYL_-_BMS]

Depends on the profile, but I reckon around 30psi - whatever you feel comfortable with.

[antix_v2]

They're 225/40's

Cheers

I thought the pressure was the same no matter what tyres? Cos it's not the amount of air you put in, it's the pressure that the tyre is at??

[DARYL_-_BMS]

NO!

[Shamrockez]

Ah well, I keep my 18s the same as my 16s and no accidents yet... :-/

[bug78]

They're 225/40's

I would of thought so. I'll ask me pal. Danke!

Hi,
In case it helps 1 bar = 14.5038 PSI

so to get PSI from Bar then multiply by 14.5038

Therefore;
2.3 Bar = 33.35 Psi

Toyo do em in that size I think. Very Euro look. Seen em on some German bugs. Nice.

in fact... from blackcircles:

Falken GRB FK 452 (Extra Load) 215/40 R18 Y £91.46
Yokohama Parada Spec 2 215/40 R18 W £150.14

[bug78]

215/40/r18 is a comon size everybody dose that


215 on a bug though you going ice raceing or sumat :D
most have 225 or 235 i thing 235 is the best fit looks more full +the grip

We got Kumho`s as a deal with the 18`s, which I thought were the cheapest of the cheap - until I was stood in the dealers the other day and noticed they are standard fit on Polo`s !
